LUMINOUS ATTACHMENT FOR INDICATIN G DEVICES.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed Ianuary 2, 1919. Serial No. 289,259.

To all whom it may concern:

Be it known that I, IRVING FLORMAN, a citizen of the United States of America, and residing in the'borough of Manhattan, city and State of New York, have invented certain new and useful Improvements in Luminous Attachments for Indicatin Devices, of which the following is a spec cation.

The invention relates to. indicating devices for example such as clocks, watches, and

V gages, to the dials and hands or pointers when folded, to the hands of a clock. Fig.

' 3 is a side whereof it is desirous to apply luminous indicating medium so that the indicating de vice may be read in darkness.

In the accompanying drawing Figure 1 represents a, plan view of a ring to be secured to the face ofa clock or other indicating device. On the ring are formed luminous fields.

Fig. 2 represents a plan view of a luminous clip in flat position to be secured,

edge view of the clip of Fig. Fig. ,4 represents the clip on lines 99 of Fig. 2. Fig. 5 represents a clock face with the ring and clip secured respectively to the clock dial and hands.

In carrying out this invention a rin 1 is formed out of paper, or other materla with points or extensions 2 thereon extending inwardly from the body hf the ring toward the center of the dial. To the points or extensions 2 a luminous material 3 is applied. The ring 1 has applied to the reverse side thereof glue or other material with which it may be aflixed around the periphery of the face of a clock dial 401 other indicating device. The face 4 of the clock dial or other indicating device, is exposed through the center opening of the ring. The

. fields-or extension 2 as illuminated are is primarily intended to be applied spaced around the ring at points'corresponding to the markings on the face of the clock dial or other devlce, which are to he indicated by the luminous material. In the drawing. Fig. 5 represents a clock face with the luminous points or extensions lying over the five minute divisions 5, on the dial. The minute graduations 6 areas The ring to clocks or other devices which have gone into the hands of users, although the device may also be used as a convenient method of applying luminous material to clocks or the like while still in the manufacturers hands. A lushown, not covered by the ringl'.

minous clip 7 is provided for the hands 12 of Fig. 2, folded of the indicating device. This clip is stamped out of thin sprin metal and has therein an aperture 8, sai aperture havin angles 8. The clip is bent at 99 across t e aperture as shown in Fig. 4 and the edges 10 thereof arebrought tightly together by pressure thereon and on the bend 9, thus giving the two wings 11 of the clip a tendency to cling together. One of the wings 11 of the clip 7 is given a fanciful formation such as the star 13 shown in the drawings. To this part 13 of the clip a luminous material 14 1s applled. The point of the indicating pointer or hands 12 are passed through the aperture 8. The head '12 of the pointer or hand binds or wedges into the corners of the aperture 8 and the wings 11 come into graspingcontact with the stem of the hand or pomters.

The luminous ring 1 may he made in segments forconvenience of packing and transportation. If desired, the minute graduations may be covered by the ring and new minute graduations printed on the ring. The ordinary hour figures on the clock dial are thus exposed for ordinary light readings. To read the device in darkness the luminous fields 2 in connection with the smaller hands of the clock show the hour reading and the luminous fields in connection with the larger hand shows the minute readings.

I clalm:

1. In combination in a clock, or likedevice, of a luminous clip having a perforation therein, a pointer through the perforation and a luminous device on the outer surface of the clip, a dial, a thin flexible ring at the periphery of said dial and luminous fields on said ring.

2. In combination, in a clock, a dial on the clock, luminous fields on the dial, a clip having an angular perforation therein, a pointer through said perforation, the pointer being wedged in the angular opening, a thin flexible ring at the periphery of said dial and luminous fields on said ring.

3. In combination in a clock, or the like, a clip having aluminous field thereon, said cli comprising flexible wing sections, an aperture in the clip, a pointer through the aperture and the wing sections in holding contact with the pointer, a thin flexible ring at the periphery of said dial and luminous fields on said ring.

In testimony whereof I have hereunto set my hand this 23rd day of December, 1918.
